Insights
This study evaluates a mobile health app with human coaching to improve statin adherence in adults with high cholesterol. The AdLip trial aims to enhance cardiovascular disease prevention through personalized interventions.
Area of Science:
- Cardiology
- Digital Health
- Public Health
Background:
- Elevated low-density lipoprotein cholesterol (LDL-C) is a key modifiable risk factor for cardiovascular disease (CVD).
- Suboptimal adherence to lipid-lowering medications, particularly statins, hinders effective lipid management and CVD prevention.
- Personalized, multicomponent interventions are needed to address medication non-adherence.
Purpose of the Study:
- To evaluate the effectiveness of a human coach-supported digital personal health assistant (mobile health app) intervention.
- To improve adherence to statins in adults diagnosed with hyperlipidaemia.
- To assess the impact on cardiovascular disease risk factors and patient-reported outcomes.
Main Methods:
- A multicentre, open-label, randomized controlled trial (AdLip) involving at least 376 non-adherent adult statin users.
- Participants randomly assigned to either a mobile health app intervention with human coaching or a control group.
- Primary outcome: statin adherence at 6 months (Medication Adherence Report Scale-5); secondary outcomes include LDL-C levels, motivation, self-efficacy, and quality of life.
Main Results:
- This section is not available in the provided abstract.
- Further analysis will be conducted using an intention-to-treat approach.
Conclusions:
- The AdLip trial will offer evidence on a multicomponent strategy for statin non-adherence in a multi-ethnic Asian population.
- Findings may guide personalized interventions for non-adherence and long-term CVD prevention.
- Trial registration: ClinicalTrials.gov NCT06614049.
Background:
Elevated low-density lipoprotein cholesterol is one of the major modifiable risk factors for cardiovascular disease. Lipid management is integral to primary and secondary prevention of cardiovascular disease, but undermined by high prevalence of non-adherence to lipid-lowering medications. Innovative, personalized multicomponent interventions may address the gaps in medication non-adherence. We aim to evaluate the effectiveness of a human coach-supported digital personal health assistant (mobile health app) intervention in improving adherence to statins in adults with hyperlipidaemia.
Methods:
AdLip is a multicentre, open-label, parallel, two-arms, randomized controlled trial aiming to recruit a minimum of 376 adult participants who are non-adherent to statins from primary care ambulatory clinic setting in Singapore. Participants recruited will be randomly assigned (1:1) to human-coach supported mobile health app intervention or control group. The primary outcome will be adherence to statins at 6 months, measured by Medication Adherence Report Scale-5. Secondary outcomes will include change in serum low-density lipoprotein cholesterol levels, health motivation and attitudes, self-efficacy, self-care behaviours, quality of life, app acceptability, user engagement, and cost-effectiveness. Outcomes will be analysed using intention-to-treat approach.
Discussion:
The AdLip trial will provide empirical evidence on a multicomponent approach to the long-standing challenge of suboptimal adherence to statins in a multi-ethnic Asian setting. Findings from this study may inform a more personalized approach to addressing non-adherence in the short term, and how it relates to cardiovascular disease prevention in the longer term. Trial Registration: ClinicalTrials.gov NCT06614049.
